Potamides: Mapping Dark Matter Halo Shapes from Stellar Stream Tracks in the Local Universe
Sirui Wu, Nathaniel Starkman, Sarah Pearson +3
Stellar streams trace the gravitational potential of their host galaxies and offer a direct probe of dark matter halo geometry. Cosmological simulations predict that halo shapes de…
A stellar stream around the spiral galaxy Messier 61 in Rubin First Look imaging
Aaron J. Romanowsky, David Martínez-Delgado, Giuseppe Donatiello +2
We present the first stellar stream discovered with the Vera C. Rubin Observatory, around spiral galaxy M61 (NGC 4303) in Virgo First Look imaging. The stream is narrow, radially-o…
Stellar tidal streams around nearby spiral galaxies with deep imaging from amateur telescopes
David Martinez-Delgado, Michael Stein, Joanna D. Sakowska +26
Tidal interactions between massive galaxies and their satellites are fundamental processes in a Universe with L-Cold Dark Matter cosmology, redistributing material into faint featu…
Extragalactic Stellar Tidal Streams: Observations meet Simulation
Juan Miro-Carretero, Maria A. Gomez-Flechoso, David Martinez-Delgado +11
According to the well established hierarchical framework for galaxy evolution, galaxies grow through mergers with other galaxies and the LambdaCDM cosmological model predicts that…
Extragalactic Stellar Tidal Streams in the Dark Energy Survey
Juan Miro-Carretero, David Martinez-Delgado, Maria A. Gomez-Flechoso +7
Stellar tidal streams are a key tracer of galaxy evolution and have the potential to provide an indirect means for tracing dark matter. For the Local Group, many diffuse substructu…
A search for stellar tidal streams around Milky Way analogues from the SAGA sample
Juan Miro-Carretero, David Martinez-Delgado, Silvia Farras-Aloy +6
Context. Stellar tidal streams are the result of tidal interactions between a central galaxy and lower mass systems like satellite galaxies or globular clusters. For the Local Grou…
A giant umbrella-like stellar stream around the tidal ring galaxy NGC 922
David Martinez-Delgado, Santi Roca-Fabrega, Juan Miro-Carretero +6
Tidal ring galaxies are observed rarely in the local universe due to their intrinsically transient nature. The tidal ring structures are the result of strong interactions between g…
Once in a blue stream: Detection of recent star formation in the NGC 7241 stellar stream with MEGARA
David Martinez-Delgado, Santi Roca-Fabrega, Armando Gil de Paz +23
In this work we study the striking case of a narrow blue stream around the NGC 7241 galaxy and its foreground dwarf companion. We want to figure out if the stream was generated by…
Hidden depths in the local Universe: The Stellar Stream Legacy Survey
David Martinez-Delgado, Andrew P. Cooper, Javier Roman +26
Mergers and tidal interactions between massive galaxies and their dwarf satellites are a fundamental prediction of the Lambda-Cold Dark Matter cosmology. These events are thought t…
